Unable to check digital signature information of other company's software

I applied a digital signature using the steps below, but I cannot confirm the signature information of other companies' software.

① Sign using another company's digital signature using ``Use certificate'' and ``Digital certificate'' in Adobe Acrobat reader.

②In Adobe Acrobat, request the recipient to sign from "Request electronic signature"

③ After signing at the other party, a signed file is created.

④ When you open the final file, the signature information is only Adobe, and you cannot confirm the signature information performed in ①.

If you use Adobe Acrobat Sign, will other signature information be deleted?

This time, since digital signatures have been registered with the government, we are responding using multiple applications.
